This Synergy Series SS102P, dual 10" subwoofer and amplifier combo by MA Audio, retails for $399.99 plus tax. This package includes a 800-watt 2-channel amp, amplifier wiring kit, two 400 watt 10" subs, and a sealed dual 10" sub enclosure that all combine for some heavy low-frequency reinforcement in your vehicle. Just add speaker wire, and you've got a complete system that will transform your music on the road. The 2-channel amp drives your sub system with 400 watts power per channel. The thermal management system dissipates heat and saves power, so this amp will run reliably for years to come. The low-pass filter puts you in command of the frequencies that reach your subs, while the variable bass boost is armed with plenty of low-end punch. The preloaded and prewired (4 ohm) enclosure features high-grade, MDF construction and is specially designed to combat resonance by reducing vibrations. Complete with a full 1 year warranty and our 30 day money back guarantee.
